Which one of the following is the correct value of the force of Earth’s gravity acting on a body of mass 1 kg?

The force of Earth’s gravity acting on a body is given by the formula F = m x g, where F is the force, m is the mass of the body, and g is the acceleration due to gravity. On Earth, the standard acceleration due to gravity is approximately 9.8 m/s² ; option [B]. For a body with a mass of 1 kg, the force of gravity can be calculated as follows: F = 1 kg x 9.8 m/s². This results in a force of 9.8 Newtons. Therefore, a body of mass 1 kg experiences a gravitational force of 9.8 N when subjected to Earth’s gravity.
This value is critical for understanding basic physics principles and is commonly used in various calculations involving weight and gravitational forces. Thus, the correct option is [B] 9.8 N, which accurately represents the gravitational force on a 1 kg mass at the Earth’s surface.
